ABSTRACT:
A cap, spinner, and discharge nozzle assembly for use with a liquid dispensing apparatus such as a trigger sprayer. The spinner assembly can be externally fitted to the discharge nozzle, and includes an annular chamber surrounding a central post having a swirl chamber in its top. The central post includes longitudinal grooves, communicating with tangential grooves in an annular wall defining the swirl chamber. Apertures are provided in the base of the annular chamber such that pressurized liquid flows through the apertures and into the annular chamber, with a resulting reduction of velocity, and then along the longitudinal grooves and through the tangential grooves into the swirl chamber. A cap is provided which variably engages the discharge nozzle and which has at least a central projection on the inner side of its front face, and preferably an annular groove formed by an outer projection surrounding the central projection. The central projection may reversibly seal against the floor and/or annular wall of the swirl chamber, and the annular groove may seal over the annular wall.
